Amphibians are vulnerable to extinction owing, partly, to altered physiological processes induced by projected global warming and drying. Understanding the mechanisms behind their responses is essential to formulate adaptation strategies for their conservation. Puerto Rico harbors 15 endemic Eleutherodactylus frogs considered vulnerable to extinction due to poor vagility and sensitivity to environmental variability. Herein are reported the effects of four temperature treatments (15, 20, 25, and 30 degrees Centigrade) on metabolic rates associated with specific dynamic action (SDA) and standard metabolic rates (SMR) of four representative species of Eleutherodactylus employing a respirometer. All species in either...
Translocating individuals of Eleutherodactylus frogs to alternative, suitable habitat is an adaptation strategy designed to minimize the impact of projected warming and drying in Puerto Rico. The action increases species persistence by increasing spatial redundancy, but it could also be used to supplement extant populations. We released 34 Eleutherodactylus coqui to determine initial, post-release survival under two treatments – non-translocated (N = 14), and translocated (N=20) to a different location 0.8 km away, but sharing similar habitat and environmental conditions. We defined “initial” as the first 17 days post-release, a period where we hypothesized that translocated individuals would have lower survival...

The U.S. Fish and Wildlife Service and the Puerto Rico Department of Natural and Environmental Resources need to develop a plan of action to help the recovery of two endangered species in the genus Eleutherodactylus (commonly known as “coqui”), while also reducing the risk that 14 other coqui species would be added to the Endangered Species list. Prior work by these researchers has identified factors influencing life history for three representative species (E. wightmanae, E. britonni, and E. antillensis) including where species occur, their abundance, and key drivers of reproduction, all of which are driven by climate and land use change. For this next research stage, this project will: (1) characterize the ability...
